Why? Because they're scared and terribly worried about our future as capitalist-driven global warming races past the old 1.5°C do-not-cross line.
__________________________________
“The goal to avoid exceeding 1.5C is deader than a doornail. It’s almost impossible to avoid at this point because we’ve just waited too long to act,” said Zeke Hausfather, a research scientist at Berkeley Earth. “We are speeding past the 1.5C line in an accelerating way, and that will continue until global emissions stop climbing.”
The 1.5C target now appears to be simply a rhetorical rather than scientifically achievable one. “I never thought 1.5C was a conceivable goal. I thought it was a pointless thing,” said Gavin Schmidt, a climate scientist at NASA.
“I’m totally unsurprised, like almost all climate scientists, that we are shooting past it at a rapid clip," Schmidt said. "But what matters is we have to reduce emissions. Once we stop warming the planet, the better it will be for the people and ecosystems that live here.”
As the world barrels past 1.5C there lie alarming uncertainties in the form of runaway climate “tipping points,” which once set off cannot be halted on human timescales, such as the Amazon turning into a savanna, the collapse of the great polar ice sheets, and huge pulses of carbon released from melting permafrost.
“1.5C is not a cliff edge, but the further we warm up, the closer we get to unwittingly setting off tipping points that will bring dramatic climate consequences,” said Grahame Madge, a climate spokesman at the UK Met Office.
“We are edging ever closer to tipping points in the climate system that we won’t be able to come back from; it’s uncertain when they will arrive, they are almost like monsters in the darkness,” Madge said.
Hausfather added, “Every tenth of a degree matters. All we know is that the more we push the climate system away from where it has been for the last few million years, there be dragons.”

An international team of scientists using observations from satellites found evidence that Earth's total amount of freshwater dropped abruptly starting in May 2014 and has remained low ever since. The researchers say the shift could indicate Earth's continents have entered a persistently drier phase.
From 2015 through 2023, satellite measurements showed that the average amount of freshwater stored on land — that includes liquid surface water like lakes and rivers, plus water in aquifers underground — was 290 cubic miles (1,200 cubic km) lower than the average levels from 2002 through 2014. According to Matthew Rodell, one of the study's authors, "That's two and a half times the volume of Lake Erie lost."
It remains to be seen whether global freshwater will rebound to pre-2015 values, hold steady, or resume its decline. Considering that the nine warmest years in the modern temperature record coincided with the abrupt freshwater decline, Rodell said, "We don't think this is a coincidence, and it could be a harbinger of what's to come."

In August and September, huge portions of South America were shrouded in intense smoke from wildfires raging in the Amazon and other parts of Brazil and Bolivia. The Brazilian Pantanal — the world’s largest tropical wetland — had an almost eightfold increase in wildfires this year compared to 2023. From Manaus to São Paulo and Buenos Aires, the smoke, visible from space, blurred sunlight for weeks and posed a threat to the health of millions.
The occurrence raised alarms, but some experts warn that in the future, it might not be such an extraordinary episode.
South America is becoming drier, warmer, and more flammable, according to a new study. These conditions favor not only natural wildfires but also the uncontrolled spread of human-caused fire.

Scientific American Loses Its Bold Leader

Anybody who can be convinced that something is true against evidence otherwise is wide open to being convinced regarding denialism — of anything. HIV/AIDS, COVID, transgender, sexism, racism, etc.
Which is why political efforts to defeat denialism will never work. The only way to defeat it is through education, from kindergarten up. All age groups, all the time.

Trees and land absorbed almost no carbon dioxide (CO2) last year, and scientists are struggling to work out why.
Carbon sinks, such as forests, oceans and soils, are an essential part of regulating the Earth’s climate. Through natural processes, these land and ocean masses absorb almost half of all human carbon emissions from the atmosphere.
But preliminary findings for 2023 – the hottest year ever recorded on Earth – have found that the amount of carbon absorbed by forests, plants, and soil has temporarily collapsed.
This was completely unexpected, and therefore not something factored into most predictions and calculations about how quickly the Earth will heat up as a result of climate change. The breakdown of the land carbon sink could be temporary, but if it isn’t, this will drastically increase the rate of global heating.
It will be impossible for the world to reach net zero without carbon sinks, because there is simply no human technology that can absorb carbon on the same scale as the forests, grasslands, peat bogs, and oceans of the world.

There is no sign of the transition away from burning fossil fuels that was pledged by the world’s nations a year ago, with 2024 on track to set another new record for global carbon emissions.
The new data comes from the Global Carbon Budget project, a collaboration of more than 100 experts led by Prof Pierre Friedlingstein, at the University of Exeter, UK, who said: “The impacts of climate change are becoming increasingly dramatic, yet we still see no sign that burning of fossil fuels has peaked. Time is running out and world leaders meeting at Cop29 must bring about rapid and deep cuts to fossil fuel emissions.”

The Copernicus Climate Change Service, a European Union organization that monitors global heating, announced on Thursday that the year 2024 will be 1.5 degrees Celsius warmer than pre-industrial levels. That means humanity has passed a critical threshold established in 2015 in the Paris climate accord.
“After 10 months of 2024, it is now virtually certain that 2024 will be the warmest year on record and the first year of more than 1.5ºC above pre-industrial levels," Samantha Burgess, deputy director of the Copernicus Climate Change Service, said in a statement. "This marks a new milestone in global temperature records and should serve as a catalyst to raise ambition for the upcoming Climate Change Conference, COP29.”
The EU agency announced this moment as nations all over the world gather in the Azerbaijani city of Baku for the 29th Conference of the Parties. The ERA5 dataset found that global temperatures in 2024 were on average 1.55 degrees Celsius higher than the 1.48 degrees threshold measured in 2023. The report also noted climate change-fueled major weather events in 2024 such as torrential floods in Spain and rapidly melting Antarctic sea ice.

Turning away from it and closing our eyes does not change things. I believe it's important to know just where we stand and what we face so we can make the best choices in how we should live.
Also, note that this essay was published before this week's disastrous US election, which means that you can expect conditions warned about here to get even worse, sooner rather than later.
_______________________________________
In recent years, environmental warnings have become impossible to ignore. Humanity has pushed Earth far beyond its natural limits, launching it into a cascade of intertwined disasters that scientists now call the “polycrisis.” No longer a distant threat, this crisis is unfolding before us, destabilizing the foundations of ecosystems, economies, and communities worldwide.
While some hold out hope for a turnaround, the brutal truth is that we are too far gone. The trajectory is set, the damage done, and there is no miracle solution on the horizon. Our only option is to live through this polycrisis as best we can, facing an uncertain and increasingly harsh reality.
As temperatures climb, ecosystems crumble, and resource conflicts rise, it’s clear that our world will never be the same. For those of us with young families, our hopes are tempered by a haunting reality: the future we once dreamed of has shifted beyond reach. What remains is an obligation to understand the forces shaping this collapse, accept the inevitability of hardship, and try to adapt as the familiar falls away.
_______________________________________
The essay includes sections on climate change, biodiversity loss, economic and social erosion, and finally, "living through the polycrisis." I hope you'll find it helpful.
